Milk test for calibration and reference values by water test
This test is performed by collecting milk of individual cows into a bucket, measuring it and
comparing the amount with the reading of the milk meter. Then, statistical deviation
calculations are done to indicate the accuracy level of the device.
It is very important to carry out a proper scaling procedure to ensure accurate scaling in
accordance with regulations.
To carry out the scaling procedure, an electronic weighing scale and a few milk buckets are
required. This chapter describes the correct procedure of scaling and statistical calculations.
If deviations in measurements are found, correct those by adjusting G&H values as
described above.
Before performing the test the following parlor tests and checks should be carried
out:
o
Milk meters are cleaned properly. Verify functionality and operation of each unit.
o
Consumable rubber parts (upper and lower gaskets, diaphragm and valve gaskets)
are replaced as recommended, and seem flawless and clean.
o
Clean air line is drained of water, milk meter solenoid air inlet is properly connected
to the clean air line and to the vacuum supply.
o
Test the vacuum level and stability. Ensure vacuum level above 30 kPa.
7.3.2.1
Collecting the Milk into a Milk Bucket
Per international regulations the following rules are adopted for scaling:
o
Multiple attachments measurements are
not
included in the statistics.
o
Only milking claw air admission is allowed. Tests may not be valid if liners cracks or
piping holes allow additional air intake by the system. Furthermore, tests where
liner slippage or large udder causing squawks (liner slip) occurs are also rejected.
